Software Testing Overview with Key Terms,
Concepts & Exam Insights 2025/2026.
Bug
An error in software that causes it to produce incorrect or unexpected results.
Defect
A flaw in the software that can lead to a failure.
Error
A mistake made by a programmer that results in incorrect code.
Failure
The inability of a software system to perform its required functions.
Fault
A condition that causes a software system to fail.
Mistake
An incorrect action or decision made by a person.
Quality
The degree to which a software product meets specified requirements and customer expectations.
Risk
The potential for loss or damage when a threat exploits a vulnerability.

Test Execution
The process of running the test cases on the software application.
Test Reporting
The documentation of the results of testing activities.
Defect Management
The process of identifying, documenting, and addressing defects in software.
Test Coverage
A measure of how much of the software has been tested, often represented by a traceability matrix.
Test Metrics
Quantitative measures used to assess the quality and effectiveness of testing.
User Acceptance Testing
A type of testing conducted to determine if a system satisfies the acceptance criteria and is ready for
use.
Automation Testing
